CVE-2018-0878

Estado: ModificadaBaja (3.1)—💥 Exploit

Windows Remote Assistance en Microsoft Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, Windows 8.1 y RT 8.1, Windows Server 2012 y R2, Windows 10 Gold, 1511, 1607, 1703 y 1709, Windows Server 2016 y Windows Server en su versión 1709 permite una vulnerabilidad de divulgación de información debido a la forma en la que se procesan los XEE (XML External Entity). Esto también se conoce como "Windows Remote Assistance Information Disclosure Vulnerability".

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
